NodeInterface<R> class abstract

You can use this class to add loading and error states to your nodes

Signal<bool> isLoading

NullableSignal<Object> error

//A separate signal for full screen loading
Signal<bool> fullScreenLoading

//You can use the `loading` method to wrap any async operation
//so you don't have to handle the loading state yourself
Future<T> loading<T>(
   Future<T> future, {
   bool invokeLoading = true,
   //If you want to show a full screen loading, just set this to true
   bool fullScreen = false,
 })
